This 1981 toga-ripper, stop-action special effects pioneer Ray Harryhausen's last film, chronicles a war between the gods that threatens to destroy the world. Born of a god but raised as a man, Perseus (Harry Hamlin) volunteers to lead a dangerous mission to defeat a vengeful Hades (Jack Gwillim) before he can seize power from Zeus (Laurence Olivier) and unleash hell on earth. Battling fearsome beasts ("Release the Kraken!") and unholy demons, such as the snake-haired Gorgon Medusa, Perseus must accept his power as a god, defy fate, and forge his own destiny in order to succeed.
